. Heretofore among other features liquid fuelburners havebeenconstructed to include a casing or shell, and a wick holder therein,adapted to retain a wick, and devices for raising and lowering the wickholder to adjust the wick to various positions. Sofar as I am aware, thedevices heretofore employed for adiusting the wick to position havecomprised various means 7 for engaging the wick holder at one portionthereof. As commonly constructed the wick holders aremade of sheetmaterial, and are tubular in form, and consequently. by engaging oneportion onl of the ick holder to move the same withinthe casing there isa. tendency to move the portion of the wick holder directly engaged to agreater extent than other portions thereof- It naturallyfollows thatthere is the efore created a tendency for the wick holder to wedge inerence has hereinbefore been made. and to provide in a liquid fuelburner a wick hold- I er. and devices for actuating the same'in such .amannerthat "oppositely disposed portions of the wick holder aresimultaneously engaged and uniformly moved so as to produce a right'linemovement in all parts of the wick holder, thereby preventing any,tendencv'of the wick holder to wedge in the casing. and also insuring auniform projection of the end of the wick beyond the peripheral portionof the casing to effect a resulting uniform flame from'all portions ofthe wick when the burner is in use, as will be hereinafter moreparticularly described.

"In the drawing: 1

1 Fig. 4: is a'plan of the spindle and associated parts employed foractuating the wickholden-and v V Fig. 5 is anelevation on a reducedscale,

illustrating the wick holder and wick contained therein.

By referenceto the drawing it will. be seen that in carrying out theinvention the liquid fuel burner made in accordance" therewith comprisesa casing haying an outer .wall 10, and aninner'wall 11. In correspondingpositions as illustrated the outer wall 1t) may be provided with a rib12. and the wall UNITED TATES PATENT OFFICE.

11 with an internal rib 13. although. the ribs 12 and 13 play no part inthis invention. At

the inner or. lower ends theouter and inner Walls 10 and 11 are suitablyinterlocked as indicated at 14 to connect these walls ,to one another.in concentric relationship so as to provide-between them an annularspace 15 'for a wick and. wick holder as hereinafter described.

In a suitable position in the'outer wall 10.

thesame is apertured and fitted with aring 16:.suitablv connected tothis ring 16 there is aitapped socket 17 fitting. within the socket 17and abutting against the outer face of the ring 16 I employ a collar 18.As illustrated. a portion of this collar isadapted to fit within thering. andthe collaris provided witha shoulder forengagement with theouter face of the ring. I also employ a plug 19 that is,exteriorlyscrew.threaded so as to be turned down into the socket 17.and, at one end is provided with a head 20, which may be square asindicated, or hexagonal. or providedwith any number of sides so as to beengaged by a wrench. The collar 18 and'the plug 19 have centrallydisposed bores therein through which a shaft 21 passes.

At its outer end this shaft 21 is fitted with a hand wheel 22. which ispreferably knurled, and by whichthe shaft and parts connected theretomay be readily turned either one direction or the other. The shaft 21may be an integral part of a ribbed rod 23, orsuitably connectedthereto. The ribs on the rod are indicated at 23', and as will beunderstood these ribs form a series of extended or elongated teeth.- Ina position. in alignment with the ring 16 in the outer wall 10 the innerwall 11 is aper- 1 tured as indicated at 24. In a substantiallydiametrically opposite position this inner wall 11 is similarlyapertured at- 25. These apertures 24 and 25 are of such a diameter as toreceive and act as bearings for the end portions of the. ribbed ortoothed rod 23. Extending substantially diametrically across'the innerwall 11 there is a sleeve 26, which surrounds and also acts as a bearingfor a ribbed or toothed rod 23. As illustrated, the apertures 24 and 25in the inner wall 11 may be defined by inwardly extending flanges, andthe extremitiesof the sleeve 26 fitted over and secured to theseflanges. It will be understood however, that this construction is merelyillustrative, and may be made in any other suitable manner. Also asillustrated, the outer portion of the collar 18 and the inner end of theplug 19 may be suitably recessed so as to provide for a packing 27 tosurround the shaft 21, and to make a tight joint between the same andthese parts.

Between the outer and inner walls 10 and 11 there is a wick holder 28with a wick 29 carried thereby. In oppositely disposed positions thewick holder 28 is slotted as indicated at 30. vThese slots extendlongitudinally a predetermined distance, and corresponding edgesdefining like sides of the slots areprovided with teeth 31 and 32forming racks, which are simultaneously, en-

, gaged by the end portions of the ribbed or toothed rod 23, which aswill be understood act as pinions in engaging the teeth of these racks.The length of the ribbed or toothed portion of the rod 23 issubstantially the same as the diameter of the outer wall 10, so that asclearlyshown in Figs. 1 and 2 of the drawing the extremities of theribbed or toothed portion of the rod engage the teeth 31 and 32, ashereinbefore stated.

' It will now be understood that as the shaft 21 is turned the teeth 23engage the teeth 31 and 32 of the wick holder simultaneously, andconsequently there is a corresponding motion imparted at the same timeto oppositely disposed sections of the wick holder.-

This causes a uniform motion in either direction of the wick holderbetween the outer and inner walls, and a corresponding motion of thewick, resulting as will be appreciated in the outer end of thewick'extending uniformly in all its parts from the outer peripheralportion of the casing. Furthermore, as will also beappreciated thisresults in preventing the wick holder from any tendency to wedge, andalso results in a uniform fiamefr'om all parts of the wick.

Although forming no part of the invention, the liquid fuel burner asillustrated,

may be supported from a supply pipe 33, by

which the fuel to be burned is conveyed to thewick. and a bracket 34extending between the supply pipe and a suitablesupp0rt 35 or otherwise.i
